It's probably not listed. We plan to provide a revamped job mechanism for editorial import that will have a UI - much like we've done for classifieds. The jobs panel as it is currently built has too many hidden options and is not self-documenting.

The authors property I looked at in the code was a property of the incoming source - it was not an option to the parser so that was my mistake. Try setting as a filter with field name set to authors, regular expression set to /^$/ and replacement set to kevin.cox@galvnews.com.

Well, I'm not sure why it's not working. It's possible there is something else preventing this from working - so at this point I'm going to file a change request to add an explicit option to the tncms parser to set the author from an option as was asked about earlier.
